Thrust roller bearings can be divided into:
1. Thrust self-aligning roller bearings Thrust self-aligning roller bearings are separate bearings. Because their load lines form a certain angle with the bearing axis, this type of bearing can simultaneously withstand radial and axial loads, and can be extremely heavy. The use of load conditions, the allowable speed is also high. Thrust spherical roller bearings can have good self-aligning performance, allowable angle error is 2 degrees - 3 degrees, but the allowable angle error decreases with the actual load applied to the bearing. Such as 292, 293 and 294 three series of bearings, when Fa +2.7Fr = 0.15Ca, its allowable angle error will be reduced to 1.5 degrees. The shaft ring is divided into two types: bushing and non-bushing.
2. Thrust Cylindrical Roller Bearing Thrust Cylindrical Roller Bearing can withstand one-way axial load, which can limit the one-way axial displacement of the bearing. It is much more than the axial load capacity of the Thrust Ball Bearing, and the rigidity is large, occupying the shaft. To the space is small. Mainly used for low bearing speed occasions.
3. Thrust Tapered Roller bearings Thrust tapered roller bearings can withstand one-way axial load, can limit the one-way axial displacement of the bearing, it is greater than the axial Thrust Bearing capacity of cylindrical bearings, the limit speed is slightly higher than the thrust cylindrical roller bearings.
4. Thrust Needle Roller Bearing thrust roller bearings use:
Thrust roller bearings are mainly used in oil drilling rigs, ocean-going cargo ship propeller shafts, combined roadheaders, overhead cranes, large tower cranes turntables, drilling machine turntables, heavy-duty machine tools, oil drilling rigs, vertical drilling rigs, etc.
